ext2_fs.h: __u32 i_ctime; /* Creation time */
sysv_fs.h: unsigned long i_ctime; /* time of creation */
ufs_fs.h: struct timeval ui_ctime; /* 0x20 creation */
umsdos_fs.h: time_t ctime; /* Creation time */
These might be wrong too:
msdos_fs.h: __u8 ctime_ms; /* Creation time, milliseconds */
msdos_fs.h: __u16 ctime; /* Creation time */
(how does one fit milliseconds in a __u8 variable?)
